摘要

吸附式制冷是一种绿色环保节能的制冷技术，在低于100℃的低品位热能如废热能、太阳能等的利用方面具有广阔的发展前景。为了能够利用这部分的能源，提出了由吸附制冷过程与再吸附过程组成的二级吸附式制冷循环。采用SrCl2-NH4Cl-NH3作为工质对，测试不同蒸发温度与冷却温度下吸附剂的吸附与解吸性能。实验测试结果表明：当热源温度为70℃时，二级吸附式制冷也能够实现-25℃下的冷量输出。在测试工况下，氯化锶的最大吸附量达到了理论吸附量的94%。80℃热源、25℃冷源以及-25℃制冷条件下二级吸附式制冷循环的COP和SCP达到了0.250与160 W·kg-1。这个数值与CaCl2-BaCl2-NH3两级冷冻在85℃驱动热源以及同等的冷源与制冷温度条件下的数据相对比，驱动热源需求降低了5℃，COP提高了4%，SCP提高了10%以上。

Abstract

Adsorption refrigeration is an environmental benign and energy saving refrigeration technology and has a great potential for the utilization of low-grade energy

such as solar energy and industrial waste heat below 100℃.For efficient utilization of these low-temperature heat sources

a two-stage adsorption refrigeration cycle was proposed based on the adsorption refrigeration process and resorption process. Refrigeration performance of the working pair of SrCl2-NH4Cl-NH3 was tested at different evaporating and condensing temperatures.The results show that the two-stage adsorption refrigeration cycle can give the cooling output with the temperature of -25℃ when the temperature of the heat source is 70℃.The adsorption quantity of strontium chloride is 94% of the theoretical value.Under the condition of 80℃ heat source

25℃ cooling source

and -25℃ refrigerating temperature

the COP and SCP are 0.250 and 160 W·kg-1

respectively.At the same cooling and refrigerating temperatures

compared with the working pair of CaCl2-BaCl2-NH3 with the heat source temperature of 85℃

the heat source temperature in this study decreases 5℃

and COP and SCP increase by 4% and 10%

respectively..
